Specification of Letters Patent Patented Dec. 13, 1921.

Application filed November 16, 1918. Serial No. 262,915.

T 0 all whom it may concern:

Be it known that I, LOUIS T. FREDERICK, a citizen of the United States,and a resident of Wilkinsburg, in the county of Allegheny and State ofPennsylvania, have invented anew and useful Improvement inHeat-Regulating Attachments for Tube- Machines, of which the followingis a specification.

My invention relates to heat-regulating devices for tube machines, andit has for its primary object the regulation of the amount of heattransmitted to sheet material which has previously been treated with anadhesive and is to be automatically wound upon mandrels to form tubes.

Heretofore, it has been customary, in heating. treated material which isbeing wound to form tubes, to employ a heating device in which heatregulation has been accomplished by varying the amount of heat deliveredto the heating device, and, subsequently, transmitted to the treatedmaterial. This method, however, is subject to criticism on account ofits inability to provide quick regulation and because of the constantattention required by it throughout the operation. In view of this, oneobject of my invention is to provide a heat-regulating device, for tubemachines, which shall respond quickly to regulation and, therefore,require less attention while in operation.

A further object of my invention is the provision of a heat-regulatingattachment, for tube machines and the like, which shall so eflicientlycooperate with the machine to which it is attached that a more uniformand better product 'shall result.

A still further object of my invention is the provision ofheat-regulating devices, for

tube machines, of great durablity and of such construction that allparts shall be easily accessible for repair work.

WVith these and other objects in view, my invention will be more fullydescribed, illustrated in the drawings, in which corresponding numeralsindicate like parts, and then particularly pointed out in the appendedclaims.

In the drawings Figure 1 is an end view of a tube machine having aheat-regulating device attached thereto that embodies my invention; Fig.2 is a side view of the machine and the heat-regulating device shown inFig. 1, and Fig. 3 is a longitudinal sectional view of the heating rollshowing an electrical heating coil disposed therein.

A tube machine, of the well known Haefely type, has been employed toillustrate, in the drawings, the character and mode of operation of myimproved heatregulating device and, on account ofthe well knownconstruction of such machines, only-a brief description will be givenherein.

In Figs. 1 and 2 is shown a tube machine 1 to which my improvedheat-regulating device may be adapted. The tube machine 1 here shown,has a frame 28 the inner faces of which are provided with channels 29 toreceive, and permit movement of, portions of a frame 30, which support apressure roll 31. The frame 30 and the pressure roll 31 may be raisedand lowered by any suitable means (not shown), and the right degree ofpressure to be exerted may be delicately governed by adjusting a handwheel 33. A roll 34, which may be driven by any suitable means, notshown, is journaled in brackets with which the frame 28 is provided andserves, with the aid of a heating roll 35, to support a mandrel 36. Theheating roll 35' is mounted upon' brackets 37 pivotally fastened to theframe 28, the brackets 37 being provided with gear-segments 38. Pinions39 are suitably disposed to mesh with the gear-segments 38, and gearwheels 40, which have a rigid and concentric relation to the pinions 39,mesh with gear wheels 41 mounted upon a shaft 42 having a hand wheel A3.A pawl 44 engages one of the gear wheels 11 to hold theparts' in theiradjusted positions.

The operation and adjustment of the heating device, embodied in themachine shown in Figs. 1 and 2, involves the hand wheel 43 being sooperated as to actuate the gear wheels 11 to impart movement to thepinions 39 through engagement with the gear wheels 40. The pinions39,meshing with the gear: segments 38, tend to raise or lower thebrackets 37 and the heating roll carried by them. according to thedirection in which the hand wheel 42 may be turned. The heating roll 35transmits a quantity of heat to treated material passed over it inaccordance with the degree of engagement of the roll with the material.The roll 35 may be heated by any suitable means, such as an electricalcoil 32, shown in Fig. 3. The heat imparted to the treated material maybe controlled gear segments, pinions material passing over it engages itto a v the appended claims.

I cla1m as my invention? 1. In a heat-regulating device for tubemachines andthe like a heating roll and ad justable su ports therefor.

. 2. In a eat-regulating device for tube machines and the like a heatingroll, adjustable supports therefor and. means for ad'- justingsaidsupports.

3. In a heat-regulating device for tube machines and the like, a heatingroll and means for adjusting the position of the heat-' ing roll to varythe extent of its engagement with treated material passed over. it.

4. In a heat-regulating device for tube machines and the like, a heatingroll, adjustable supports therefor provided with disposed in engagementwith the gear'segments and means for rotating the pinions.

v5. In a heat-regulating device for tube machines and the like, aheating roll, adjustable supports therefor provided with gear segments,pinions disposed in engagement with the gear segments, means forrotatingthe pinions and means for maintaining. the pinions in-anyadjusted position.

6. In a heat-regulating device for tube machines and the like, aplurality of movable brackets provided with gear segments, a heatingroll supported by the brackets, a

plurality of pinlons adapted to engage the' gear segments, means foractuating the pin- 1ons and means for maintaining the pinions in anyadjusted position.

.7. n a heat-regulating device for tube machines and the like, aplurality of movable brackets provided with gear segments, a heatingroll supported by the brackets, a plurality of pinions adapted to engagethe .gear segments, manually operable means for actuating the pinionsand means for maintaining the pinions in any adjusted position.

In testimony whereof, I have hereunto subscribed my name this 26th dayof Oct.,

' LOUIS T. FREDERICK.
